Das Reich committed the Oradour-sur-Glane and Tulle massacres, in August 1939 Adolf Hitler placed the Leibstandarte SS Adolf Hitler and the SS-Verfügungstruppe under the operational command of the OKH. Events during the Invasion of Poland raised doubts over the effectiveness of the SS-VT. Himmler insisted that the SS-VT should be allowed to fight in its own formations under its own commanders, Hitler was unwilling to upset either the army or Himmler, and chose a third path. He ordered that the SS-VT form its own divisions but that the divisions would be under army command, in October 1939 the SS-Verfügungstruppe regiments, Deutschland, Germania and Der Führer, were organized into the SS-Verfügungs-Division with Paul Hausser as commander. Thereafter, the SS-VT and the LSSAH took part in training while under army commands in preparation for Operation Fall Gelb against the Low Countries.

On the following day, British forces attacked Saint-Venant, forcing the SS-VT Division to retreat, on 26 May the German advance resumed. On 27 May the Deutschland regiment of the SS-VT Division reached the defensive line on the Leie River at Merville. They forced a bridgehead across the river and waited for the SS Division Totenkopf to arrive to cover their flank, what arrived first was a unit of British tanks, which penetrated their position. The SS-VT managed to hold on against the British tank force, only the arrival of the Totenkopf Panzerjäger platoon saved the Deutschland from being destroyed and their bridgehead lost. By 30 May, most of the remaining Allied forces had pushed back into Dunkirk where they were evacuated by sea to England. The SS-VT Division next took part in the drive towards Paris, after the close of the Battle of France, the SS-VT was officially renamed the Waffen-SS in July 1940.

Five businessmen founded 3M in Two Harbors, Minnesota, in 1902, originally a mining venture, the goal was to mine corundum, but this failed because the mines mineral holdings were anorthosite, which had no commercial value. Co-founder John Dwan solicited funds in exchange for stock and Edgar Ober, the company moved to Duluth and began research and producing sandpaper products. William L. McKnight, later a key executive, joined the company in 1907, 3M finally became financially stable in 1916 and was able to pay dividends. The company moved to St. Paul in 1910, where it remained for 52 years before outgrowing the campus and moving to its current headquarters at 3M Center in Maplewood, Minnesota in 1962. The new Maplewood campus is 475 acres and has over 50 buildings, the company began by mining stone from quarries for use in grinding wheels. Struggling with quality and marketing of its products, management supported its workers to innovate and develop new products, twelve years after its inception, 3M developed its first exclusive product, Three-M-ite cloth. Other innovations in this era included masking tape, waterproof sandpaper, by 1929, 3M had made its first moves toward international expansion by forming Durex to conduct business in Europe. The same year, the stock was first traded over the counter. The company is currently a component of the Dow Jones Industrial Average, the founders original plan was to sell the mineral corundum to manufacturers in the East for making grinding wheels. In reality, however, Dwan and his associates were not selling what they thought, failing to make sandpaper with the anorthosite, the founders decided to import minerals like Spanish garnet, after which sale of sandpapers grew. In 1914, customers complained that the garnet was falling off the paper, the founders discovered that the stones had traveled across the Atlantic Ocean packed near olive oil, and the oil had penetrated the stones. Unable to take the loss of selling expensive inventory, they roasted the stones over fire to remove the olive oil, the companys late innovations include waterproof sandpaper and masking tape, as well as cellophane Scotch Tape and sound-deadening materials for cars. In 1947, 3M began producing PFOA by electrochemical fluorination, during the 1950s, the company expanded worldwide with operations in Canada, Mexico, France, Germany, Australia, and the United Kingdom in large part by Clarence Sampair. DuPont referred to PFOA as C8, in 1951, international sales were approximately $20 million. In the late 1960s and early 1970s, 3M published a line of board games and these games were marketed to adults and sold through department stores, with easily learned simple rules but complex game play and depth and with uniformly high-quality components. As such, they are the ancestors of the German Eurogames, the games covered a variety of topics, from business and sports simulations to word and abstract strategy games

4 Vesta
–
Vesta, minor-planet designation 4 Vesta, is one of the largest objects in the asteroid belt, with a mean diameter of 525 kilometres. It was discovered by the German astronomer Heinrich Wilhelm Olbers on 29 March 1807 and is named after Vesta, Vesta is the second-most-massive and second-largest body in the asteroid belt after the dwarf planet Ceres, and it contributes an estimated 9% of the mass of the asteroid belt. It is slightly larger than Pallas, though more massive. Vesta is the last remaining rocky protoplanet of the kind that formed the terrestrial planets, numerous fragments of Vesta were ejected by collisions one and two billion years ago that left two enormous craters occupying much of Vestas southern hemisphere. Debris from these events has fallen to Earth as howardite–eucrite–diogenite meteorites, Vesta is the brightest asteroid visible from Earth. Its maximum distance from the Sun is slightly greater than the distance of Ceres from the Sun. NASAs Dawn spacecraft entered orbit around Vesta on 16 July 2011 for an exploration and left orbit on 5 September 2012 en route to its final destination. Researchers continue to examine data collected by Dawn for additional insights into the formation, Heinrich Olbers discovered Pallas in 1802, the year after the discovery of Ceres. He proposed that the two objects were the remnants of a destroyed planet and these orbital intersections were located in the constellations of Cetus and Virgo. Olbers commenced his search in 1802, and on 29 March 1807 he discovered Vesta in the constellation Virgo—a coincidence, because Ceres, Pallas, and Vesta are not fragments of a larger body. Because the asteroid Juno had been discovered in 1804, this made Vesta the fourth object to be identified in the region that is now known as the asteroid belt, the discovery was announced in a letter addressed to German astronomer Johann H. Schröter dated 31 March. Gauss decided on the Roman virgin goddess of home and hearth, Vesta was the fourth asteroid to be discovered, hence the number 4 in its formal designation. The name Vesta, or national variants thereof, is in use with two exceptions, Greece and China. In Greek, the name adopted was the Hellenic equivalent of Vesta, Hestia, in English, in Chinese, Vesta is called the hearth-god star, 灶神星 zàoshénxīng, in contrast to the goddess Vesta, who goes by her Latin name. Upon its discovery, Vesta was, like Ceres, Pallas, the symbol representing the altar of Vesta with its sacred fire and was designed by Gauss. In Gausss conception, this was drawn, in its modern form, after the discovery of Vesta, no further objects were discovered for 38 years, and the Solar System was thought to have eleven planets. However, in 1845, new asteroids started being discovered at a rapid pace and it soon became clear that it would be impractical to continue inventing new planetary symbols indefinitely, and some of the existing ones proved difficult to draw quickly. That year, the problem was addressed by Benjamin Apthorp Gould, who suggested numbering asteroids in their order of discovery, thus, the fourth asteroid, Vesta, acquired the generic symbol ④

1st Cavalry Division (United States)
–
The 1st Cavalry Division is a combined arms division and is one of the most decorated combat divisions of the United States Army, as well as the other four branches of the U. S. military. It is based at Fort Hood, Texas, as of 2013, the 1st Cavalry Division is subordinate to III Corps and is commanded by Major General John C. Thomson III. The history of the 1st Cavalry Division began in 1921 after the established a permanent cavalry division table of organization. Since 1st Cavalry Division was to assemble from existing units, it was able to go active in September 1921, even though the subordinate units did not arrive completely until as late as 1922. 1st Cavalry Division was assigned to the VIII Corps Area, with its headquarters and 2d Brigade located at Fort Bliss, Texas. The 1st Cavalry Division’s assembled at Douglas, Arizona, the 1st, 7th, and 8th Cavalry Regiments had previously been assigned to the wartime 15th Cavalry Division until they were returned to the VIII Corps Area troop list on 12 May 1918. 1st Cavalry Regiment remained assigned until it was transferred to 1st Cavalry Division on 20 August 1921 and this controversy continued until 18 December 1922, when the 5th Cavalry Regiment, then on the VIII Corps Area Troop List, swapped places with the 10th Cavalry Regiment. In 1923 the 1st Cavalry Division held division maneuvers for the first time, however, financial constraints made that impossible. Only in 1927, through the generosity of a few ranchers who provided land, was the division able to conduct such exercises again. In 1928 Major General Herbert B, crosby, Chief of Cavalry, faced with personnel cuts, reorganized the cavalry regiments, which in turn reduced the size of the 1st Cavalry Division. Crosbys goal was to decrease overhead while maintaining or increasing firepower in the regiment, the cavalry brigades machine gun squadrons were inactivated, while the responsibility for training and employing machine guns fell to the regimental commanders, as in the infantry. The new structure increased the size of the troop, expanded the medical unit to a squadron. A divisional aviation section, an armored car squadron, and tank company were added, the artillery battalion was expanded to a regiment. With the arrival of the 1930s, serious work started on the testing and refining of new equipment, to facilitate this, 1st Cavalry Division traded 1st Cavalry Regiment for 12th Cavalry Regiment on 3 January 1933. Like the 1937 infantry division test, the maneuvers concentrated on the cavalry regiments around which all other units were to be organized. The latter configuration allowed the division to deploy easily in two columns, which was accepted standard cavalry tactics, one headquarters would assume responsibility for the administration and disciplinary control for these forces. The special troops remained as structured in 1928, and no observation squadron or chemical detachment found a place in the division, with the paper changes in the cavalry divisions and other minor adjustments, the strength of a wartime divisional rose to 10,680. In order to prepare for war service, 1st Cavalry Division participated in the maneuvers, Toyahvale
